If f(x) = 4(3x - 5), find f-1(x)

deff fn [24]

Answer:

$f^{-1}(x) = \frac{1}{12}(x+20)$

Step-by-step explanation:

Given: f(x) = 4(3x - 5)

Is required to find f⁻¹(x)

f(x) = y = 4(3x - 5)

∴ y = 4 * 3x - 4 * 5

∴ y = 12x - 20 ⇒ add 20 to both sides

∴ y + 20 = 12x ⇒ divide both sides by 12

∴ $\frac{1}{12} (y+20) = x$

Replace the places of x and y.

∴ $y=\frac{1}{12} (x+20)$

∴ $f^{-1}(x) = \frac{1}{12}(x+20)$

Before the clowns arrived, only 35% of the children wore happy faces. If 117 children did not wear happy faces, how many childre

denis-greek [22]

Answer:

180

Step-by-step explanation:

If 35% did not wear happy faces, then 100% -35% = 65% did wear happy faces.

Then we have ...

... 117 = 65% × (all children)

... 117/0.65 = all children = 180 . . . . . . divide by 65% = 65/100 = 0.65

There were 180 children in all.
